尿素基團在主客化學上不同角色之研究

The Research of Urea Groups as part of Host or Guest

指導教授 : 梁文傑

摘要


本論文分為三部分,第一部分以具尿素基團的冠醚分子3、6為主分子研究其與鋰離子的錯合行為。我們發現化合物3、6協同錯合地與鋰離子形成1:2的錯合物,而化合物6的螢光實驗可以發現化合物6在鹼金族裡對鋰離子有選擇性。 第二部分則是將尿素與醯胺基團當成被偵測的客分子,我們合成了具雙酸根的三苯胺衍生物鹽類36,發現尿素與醯胺基團加入後鹽類36的循環伏安譜之還原電流減少可以用來偵測尿素與醯胺基團。我們發現分析物的濃度、鹽類36的濃度與Ipc0、Ipce符合下列的線性關係:[Analyte]/[36]0-{(Ipc0-Ipce)/Ipc0}=(1/K[36]0) {(Ipc0-Ipce)/Ipc0},斜率就是K值,也可說是偵測的靈敏度。 第三部分我們將原本合成具尿素基團分子的方法推展到具手性的具尿素基團化合物R-56、S-56、79。

There are three chapters in the thesis. The cooperative and selective lithium complexation of compounds 3 and 6 containing urea groups was discussed in the chapter 1. Compounds 3 and 6 form 1:2 complex with lithium ion cooperatively. The selective lithium complexation of compound 6 among ions belong to IA was found from fluorescence experiment. Urea and amide were used as guest molecule in the chapter 2. Dicarboxylate 36 shows three anodic waves and two cathodic waves in CV. The cathodic current decreased when urea and amide were added. The linear relationship of the concentration of analyte and 36, Ipc0 and Ipce was followed the equation below:[Analyte]/[36]0-{(Ipc0-Ipce)/Ipc0}=(1/K[36]0) {(Ipc0-Ipce)/Ipc0},the slope is binding constant K. The synthesis of cyclic chiral compounds R-56, S-56 and 79 containing urea groups was discussed in chapter 3.
